Apache Subversion vs Fossil

Apache Subversion is a free, open-source centralized version control system for individual users through large enterprise operations. It versions directories, files and free-form key/value properties, with atomic commits that apply only when the complete change succeeds. Branches and tags use copy operations with a small, constant space requirement, while merge tracking assists changes between development lines. File locking is optional, and selected files can require a lock before editing. Repositories can be served through Apache HTTP Server using WebDAV/DeltaV, or through the standalone svnserve server, including SSH tunneling. Subversion supports Windows, macOS and Linux, with API and self-hosted deployment options. It offers native large-file handling, sparse checkout and nested repositories. TortoiseSVN and Eclipse or NetBeans integrations are identified as separate third-party projects rather than core features. The project publishes source code, while binary packages are maintained by volunteers or other projects. Community support comes through user and developer mailing lists. Archived releases outside currently supported versions lack community support, and experimental features in the 1.14 release notes carry no backward-compatibility promise.

Fossil is a free, distributed software configuration management system for controlling and tracking software-project development and history. It combines version control with bug tracking, a wiki, forums, email alerts, chat, and technical notes. Its built-in web interface includes ticketing, documentation, timelines, full-text search, histories, diffs, ZIP downloads, and access management. Fossil is distributed as a single self-contained executable and can run as a standalone server or through CGI, SCGI, inetd, or stunnel. Official precompiled binaries are available for Linux, Mac, and Windows, and it can be self-hosted. Network communication uses HTTPS or SSH; synchronization supports autosync and manual merges, with autosync enabled by default. Repositories use an SQLite database with atomic transactions and consistency checks before commits. The project supports an automatic GitHub mirror and originated as a tool for the SQLite project. Fossil is offered under a 2-clause BSD license. Listed limitations include no file locking, large-file handling, sparse checkout, or nested repositories.
